engine driving an electric generator to supmotors, which drive ply current-to electric preferably of the the car, the engine being Diesel type. y

The object is to avoid the transmission of vibrations from the running vof the engine to the part of the car containing the passengers and the motormen,fwithout at the same time complicating the connections of the engine ator'on the other hand, by the introduction of movable join-ts, -exible sections, or otherwise. This is accomplished by placing the engine, together with its fuel and air tanks and the dynamo-generator which it drives on a truck frame, which is mounted on the wheel axles independent 'of 4the main car frame which contains the passengers and motormens compartments, the electric drive motors being disposed on one of the trucks which support the car frame.

The invention is illustrated .schematically in the accompanying drawing, wherein:

Figure 1 isa simplified longitudinal section through a car embodying the invention', with the exterior truck frame in section; and Fig. 2 is a cross-section taken at-the left of Fig. l.

rlhe portion 1 of the 'car body represents the space devoted 'to passengers, while the motormen. frame 4, comprising side and end sills, supported, adjacent the ends on two swiveled and 6, by means of bodyamdf truckbolsters 7,18 and 9,10, and king pins 11 and 12, respectively. v@ne of these truck frames carryingthe car frame is borne on the axles 13, 14 and 15 of one set ofvwheels residing at Winterthur, Canton ofv with its fuel and high pressure air sup? plies on the one hand, and the electric gener- 136, '140 and 150, and the other truck frame 6, is borne on the axles 16 and A17 of the other set of Wheels 160 and 170. The driving electric motors,shown as two 1n number, 18 and 19, are mounted on the truck frame 6 and drive the axles 16 and 17. Both vof these truck frames preferably bear on the yaxles outside o-f the wheels.

A special truck frame 20 is provided for the power installation which comprises the dynamo 21 and the Diesel engine driving it,

and is mounted on one of the sets of wheel axles carrying the car frame and body but independentof the latter. To this end the saidtruck frame is preferably borneon the Aaxles between the set of wheels 130, 140 and 150, the truck. frame 5, supporting the car frame at this end, being formed to surround the truck frame 20, which may also extend upward within the car frame 1l. Whereas thetru'ck frame 5 is, shown bearing onall three axles 18, 14C and 15, it is preferable for the truck frame 20 to rest only on the end axles 13 and 15, thereby p-roviding a longer wheel base for that truck.

The engine preferably 'comprises -twosets of cylinders 23 disposed side by side in rateateaapiigi,rela,

diagonal, upward dii/erging relation, withl a l common exhaust manifold or muffler 24 connected between them, and a fuel tank 25 disposed centrally over' the exhaust manifold. Tanks 26, holding compressed air for fuel injection and for starting, are shown ranged horizontally at the outer sides of the cylinders, and, nected with the cylinders'by suitable lines which need not be here described.'v The Various parts of the .power installations are.'

shownv housed within an extension of the motormens compartment 2.

The drawings being diagrammatic in character and being directed more particularly to the points of novelty, itfhas not been thought necessary to illustrate the springs, the electrical connections between the dynaino and motors, or other familiar features, and it will be understood that these may be of any usual or desired character.
